Cover plate, door covering and aircraft or spacecraft

Abstract

The present invention provides a cover plate for covering at least portions of a door gap formed between a door covering and a fuselage cell of an aircraft or spacecraft, comprising: a fastening portion by which the cover plate can be mounted on an outer surface of the door covering; a contact portion which rests in a contacting manner against an outer skin of the fuselage cell when the door covering is closed; at least one corner portion associated with a corner of the door covering; and a side portion associated with a side of the door covering, the at least one corner portion and the side portion being configured to press the contact portion with a constant contact pressure against the outer skin of the fuselage cell when the door covering is closed. The present invention further provides a door covering for an access opening in a fuselage cell of an aircraft or spacecraft having a cover plate of this type as well as an aircraft or spacecraft having a cover plate of this type and/or having a door covering of this type.

What is claimed is: 
     
       1. A cover plate for covering at least portions of a door gap formed between a door covering and a fuselage cell of an aircraft or spacecraft, the cover plate comprising:
 a fastening portion configured to mount on an outer surface of the door covering; 
 a contact portion configured to rest in a contacting manner against an outer skin of the fuselage cell when the door covering is in a closed position; 
 at least one corner portion associated with a corner of the door covering having a first precurvature directed towards the outer skin of the fuselage cell; 
 a side portion mounted to a side of the door covering having a second precurvature directed towards the outer skin of the fuselage cell; 
 wherein the second precurvature is not constant over an entirety of the side portion; and 
 wherein the at least one corner portion and the side portion are capable to press the contact portion with a constant contact pressure against the outer skin of the fuselage cell when the door covering is in the closed position. 
 
     
     
       2. The cover plate according to  claim 1 , wherein the second precurvature being greater than the first precurvature. 
     
     
       3. The cover plate according to  claim 1 , wherein the at least one corner portion has a first rigidity and in that the side portion has a second rigidity, the second rigidity being greater than the first rigidity. 
     
     
       4. The cover plate according to  claim 1 , wherein the cover plate comprises a core which is arranged between two skin layers of the cover plate. 
     
     
       5. The cover plate according to  claim 4 , wherein the skin layers comprise a plastics material, in particular a fibers-reinforced plastics material. 
     
     
       6. The cover plate according to  claim 4 , wherein the core comprises a plurality of core elements. 
     
     
       7. The cover plate according to  claim 6 , wherein the core elements have in each case different first or second precurvatures directed towards the outer skin of the fuselage cell and/or different rigidities. 
     
     
       8. A door covering for an access opening in a fuselage cell of an aircraft or spacecraft having a cover plate according to  claim 1 . 
     
     
       9. The door covering according to  claim 8 , wherein the cover plate is mounted on an upper edge of the door covering. 
     
     
       10. An aircraft or spacecraft having a door covering according to  claim 8 .
